I noticed that when I hit the gym I'm all boosted and ready to do anything, go anywhere, testosterone levels are high and also dopamine.

But when I am off training for long I become more submissive and lazy. I don't have high drive for anything and feel completely unmotivated and no discipline.

Is this all I'm my head or what I'm kind of a nervous and moving person so I smoke a little to feel relaxed, and I find it difficult working my self up sober but I carry on thanks to discipline. Should I stick to that?
