I decided I would like to learn a new hobby (stained glass work) as something to keep me occupied as it helps my anxiety to focus on something else.

The problem is in the back of my mind anytime I make a decision to start something new I worry that it is an impulse and this would be an expensive impulse. What do you normally do in that situation? I'm thinking that if I wait awhile and I still want to do it I'll know that it wasn't just a fleeting idea.

Do you always second guess yourself once you know you're bipolar?
