Self-organisation and a positive attitude

It should be clear from the outset that self-development is easy enough to begin with. 

Don't be late, don't be lazy, don't complain, use every minute to your advantage. If you have taken a job or a course that should bring you closer to your goal, do it diligently and qualitatively. 

If you receive a refusal, a bad evaluation, a negative result, it is not a reason to admit worthlessness and fall into despondency. Learned bad experience will eventually give a positive result. 

Try again, knock on another door, adopt experiences, observe, learn, seek help. Try to find the positive in everything.
