Advice on making a decision...

I have been thinking about doing something for over five years now. At first, it was a matter of finances that was holding me back. Then my husband wasn’t 100% on board. Now, finances are not an issues and my husband is fully supportive BUT because I’ve spent five years weighing the pros and cons and over thinking it I am struggling with deciding what to do. I would say I’m literally 50/50 now and could go either way. Each the I think I’ve made up my mind, I start to panic and change it again. I feel like I’m in a endless cycle and I desperately want and need to make up my mind for sanity sake.

I will say, that I’m aware that the more logical/practical decision would be to NOT do this. However, my fear is that I’ll always dwell on it and regret not doing it.

So...how would YOU make up your mind if you were in a similar position? Would you do it so you don’t have regrets later? Or would you not do it and deal with the possible regret and constant feelings of uncertainty?
