same thing for me tesca.... ive had many an aspiration and never stuck anything through. aikido for me is the first thing ive stuck to and really stuck to.
ive been through the wanting to leave, ive gotten bored with it. but ive just made myself go and its really been worth it. ive never felt stronger in my life in both a physical and mental sense and training has become a very large part of my life taking preference over most other activities.
if you persist it may be rewarding.
take it easy and the best with your pursuits.
