Getting to the point in cycling where you "ride for a professional team" is so hard that you really have to be passionate about it,
Having a passion for something means that you didn't choose to do the thing you're passionate about, it chose you.
If you don't feel like riding, then you should definitely be doing something else. I can see not feeling like riding when you are in mile 155 of a 200-mile ride, but the next day, I always feel guilty if I'm off the bike resting, and I can't go two full days without riding! I just wouldn't feel right.
That said, if you're going thru a low period where you're just too depressed or whatever to ride, a good way to trick yourself into riding is to put some upgrade on your bike. Slip on the race wheels or something and go test them!
