It is precisely your will to cease activity in your projects after one month of activity into the project. It's perfectly okay to collect and collate a range ideas for future consideration. It is your complete choice to decide that your new idea should have your attention and that your older idea should languish in an archive somewhere. It seems that this is a pattern that you've established in your life. Now the question is: is it your will to change this pattern such that you can initiate a project and devote yourself to that idea until "completion"?
Everybody develops patterns in our own lives. It is our own responsibility to reflect on ourselves and decide if these patterns should change today, or should we continue these patterns until our death. When we decide to change, then we need to be brutally honest about what is the pattern, then we need to be honest about what is needed to move into a better pattern.
