I'm in between jobs right now. I don't have to go to work at all. Great! Isn't it?
And I've got goals to achieve.
Yet, I don't feel like doing it at times. In fact, I only feel like doing it when it's overdue and I have time constraints. I only feel like doing it less than 20% of the time.
For example, one of my goals is to continue training for my marathon and to get washboard abs. I have the time, I have the facilities (a gym, a swimming pool and a nice park nearby). Yet I don't feel like exercising when I wake up. I have to run 10km every 2-3 days. I have to swim, I have to do sit-ups, crunches, etc. I don't feel like doing these things. Yet I know I must do it.
It's the same with any other goal, whether screenwriting, or programming, or studying, or starting a business. You won't feel like doing it most of the time when you have to do it.
Just accepting this fact is liberating.
When I know I have to do something, yet don't feel like doing it, the fact that it is not uncommon to be in such a situation allows me to do what I need to do.
