You need to separate the ”what” from the “how”.
I see a lot of people discussing presidential candidates saying things like “it’s a good policy if he can get people to support it” or “they’d be a great president if they were electable”. They also follow this same line of thinking in their own personal lives “I’d love to do this thing if only X”
First decide the “what”, then figure out the “how”.
The “what” should be an idealized version of the future. The “how” is a series of incremental steps to get there.
The policy is good. It’s not good IF.
The candidate is good. They're not good IF people support them. So just support them. If everyone who believed in the candidate would back them in this way, you would probably be 3/4 of the way there. You can then sell the rest of the people on the merits.
If you truly believe that a product or service is the right thing for the world, or a course of action is the right thing for you, then decide to do it, and find a way to get it done.
