Hello. Something to consider is that for some people big, or even medium-sized, projects and goals aren't a great fit. Some people are wired to constantly be dabbling and exploring. If you're failing to meet the goals that you're setting for yourself and then beating yourself up about it then it's worth considering a different approach.
Of course this can be easier to do in your personal life than in your work life; often at work someone else is setting the goals...
On the other hand, maybe I'm reading way too much into a couple sentences from a stranger on the internet and this doesn't apply to you...
There is a popular book that talks about accepting and embracing life as a dabbler and explorer called Refuse to Choose. (Personally I wouldn't buy it because then I would just feel bad about not reading it, but my wife told me about some ideas in it and it seems reasonable...)
