Stop waiting on others to do what I want

I’m coming to think that when I want to do something I should not even tell people about it, I should just do it. Cuz when I talk about it, others might be interested and I’m going to wait to do the activity with them but the time will pass and I’m going to end up not doing anything.
I’m tired of waisting time on others.
I also don’t want to end up doing everything by myself because I love to share the moment with others.
The answer is to do the activity only with peeps that are really interested on doing a certain thing. So I should absolutely not do all the activities with one person.
