Let's keep it concise please. I love TRP and want to improve myself. Am having difficulty with the following:

1). I want to improve efficiency when working out. I try to avoid sugar but this takes its toll on energy levels and I already have an enlarged heart (did an ECG a few months ago and the doctor said to lower the amount of workout) from working out. The funny thing? I'm skinny: 1.84 cm height, 67 kg weight. I can do 2 sets of 35-40 pushups and 2 sets of 10-12 reps with a 14 kg dumbbell. I am fit but I want to get some muscle and get leaner. How do I increase muscle mass, leanness, efficiency of exercise (please don't say gym; I love "working out with my body" -> read pushups, pullups, jogging, etc)?

2). Dietary constraints? I know you need a good diet for getting what I want from point 1). . Currently I'm trying to: avoid sugar (can't really go more than 3 days without it, and after 3 days I eat a full chocolate bar); avoid potatoes; am not eating bread; sometimes am eating fruits (usually my breakfast is 1 apple); inserting a lot of diverse vegetables and fish into my diet (fish once every few days, vegetables literally every time I have the chance); am drinking tea; am not drinking coffee; am eating seeds from time to time (sunflower seeds, walnuts, nuts, peanuts, pumpkin seeds, etc.)

3). Getting rid of zits/ fat dots? I'm not covered but I still have a lot of black dots on my nose which I can't get rid of; I still have some "fat dots" (pores literally filled with fat; sorry I don't know the English word for it) and recurring normal zits. Currently the only solution I saw (also you should use it yourselves!) is: when you're finished popping the zit, keep going! Blood will come out and that blood will coagulate -> pore is filled and the zit won't reappear.

4). Sleep rules? In essence I discovered I need a little over 7H of sleep a night to be relatively fresh the next day. I can go by the day with 6H but it makes me really sluggish. My program tends to be volatile so I don't go to bed at exactly the same hour each night. The problem starts with the fact that I wake up at the same hour each morning. Suggestions for sleep improvement?

5). Any social/ body language cues that I should use/ search for when interacting with people? There are people in my life with which I obviously want to improve relations: my co-workers, my boss, my college teachers. Suggestions?

6). Wearing shoes? As stupid as this sounds I had to add it. I walk a lot daily and I tend to walk really fast also. Because of this, the heel area of the shoes gets severely worn out in about 2 months. Suggestions?

7). Hair care? I have a lot of hair falling. It's not receding hairline; I just have less dense hair. I Googled around and found that if your hair has a white bulb at its root when it fell(mine has) then it means you're not really going bald but you're stressed or not washing enough/ correctly or not eating right or etc. Suggestions to improve hair density and resistance?

8). Where do you draw the line? TRP has an "obscure" sense of morality; where do you draw the line? (Example: do you mess around with plates if your current GF was a virgin before you and you take her virginity (this clearly has emotional impact on the chick and cares for you more)?) Any moral examples and how to handle them are MUCH obliged. I would really like to get a good sense of where the line stands. For now I consider almost nothing immoral except for playing around after you take a girls virginity.

9). Is there any way to actually improve your genes? Example: If my whole family was a family with obesity predisposition (a lot of obese people in the family), if I work out and get in shape and live an active lifestyle and do this for the rest of my life, when getting a kid, will he inherit my faster metabolism and have a skinny/ athletic/ active body? How far does this extend (am thinking about the hair from point 7). and the zits from point 3). )? Any suggestions in this area?

I will keep editing my post because I'm sure I'm forgetting things. Thanks in advance everyone.

EDIT: questions 7)., 8)., 9). added.
