I tried this before, with only 3 ideas and that was 2 too many. Sadly I ignored a mentor who told me to focus on one, and he even told me which one, and while I put more effort there, I missed a huge opportunity to get his and some other influencers support because I was distracted trying to do too much. In the end, I mostly was successful on the one idea, but it could've been far more than what I did had I listened and focused. And the other 2 ideas went almost no where except to distract me, take my money and worse my time . I was an idiot, don't be me.
Also, I want to preface this with, you can invest in multiple projects but you cannot successfully start multiple companies at once with great success. Are there exceptions to the rule, yes, but one note, they generally start with decent personal or family wealth and can hire people to focus immediately. Are you an exception? I dunno, but my guess with all respect is no, I am not either.
Pick the idea that you feel most connected too and that has opportunity there and focus and shelve the others (for now). If it doesn't work out go back and reevaluate, that would be my advice.
