With my experience in private industries here are things you guys might find helpful. You can suggest more or a edit.

Its your first job, everyone is excited. Ah! the feeling of getting up in morning and having your coffee and then commute to office. Doing that flirting with receptionist. These and some more projected image of the office we all have in mind. But reality is not this. Private job do not work like this. So keep in mind:

  1. If someone is paying you, he expect some result.
  2. There are two kind of boss, one who watch you and never correct and then fire you for not good enough. Second who always on your head, shout on you, remind you of your mistakes, made you produce the desire outcome. Second one is the best boss.
  3. Your manager is also a human. He/She was never like this, they were like you, it is the harsh job market and competition which made them like this. Respect them and you never know when your life become easier.
  4. Don't indulge yourself in office gossips. Specially for girls. Gossip started with you making sorry to customer and could end up in boss ears as you being incompetent. Office space is a race zone, you are competing with everyone. People steal someone work and show as their just to save their jobs.
  5. Office colleagues are not your friends. You are here to make money not friend. Because as soon as you or they change job, the bond weakens
  6. Don't be rude to people and build your connection. That is you job guaranty which make sure you will stay in the in industry.

For motivation:

In 1-3 years of working life: It teaches you to use your studied skills in real world, You learn to how to handle crises, pressure and penalty. Basically you have to learn lots of tits and tats. The thing they teach in collage in reality it has no use. So, if it is stinging, endure it, good time will come.

In 4-7 years: you learn people dealing, building connection. Actually this phase of your life will give you enough times to think about your long term goal. Which includes building connection, interpersonal life etc.

Beyond 8: is the time of enjoy your fruit of your labor.

Don't let any women to take all of yours hard earn money with one judgment in court.
