There is a perfect time and place for everything. This is a wonderful fantasy, but unfortunately it won't happen. There is no miracle motivator, and if you try to wait for the right time, you're going to be waiting for a long time. The answer is simple - just do it. You make up your mind and take care of what needs to be done.
Action leads to motivation, which in turn leads to more action.
I've been able to motivate myself by developing a life plan, well several life plans. I have a five-year plan, which contains the big picture of my career, and where I hope to be by then. My five-year plan simply lists everything I want to have done by the end of that period as well as the means to get there. The most important goal on my list is to have my own clinical consulting practice fully functioning. I will accomplish this through studying, reading, extra assignments, and seeking tutoring if necessary.
