If you will be looking for occasions to do something all your life - it will be very difficult for you ... It's like washing dishes. Just take and do. You can, of course, include cheering music, tune in to the fact that when you're done - get rid of duties, but you can just take the dishes and wash it because it is necessary.
If you set yourself some grandiose, large-scale goal and without doing almost anything you refuse it - this is often due to the fact that you are waiting for a quick result, and not seeing it - are disappointed. You need to convince yourself that your goal may not bear fruit soon, but when you reach the end of the path, success will be visible.
Just do everything to achieve the goal. Whip, but do it. Summing up at the end of the day, you will be proud that you worked on yourself, and did not lie on the couch.
