I also think your mentality changes over the course of the search. At first you might be very picky, thinking the ideal business is still out there, so you don't want to commit yourself to something. So you wait, or don't aggressively pursue things. Then, you realize you can't look forever, you're searching $$ starts to run out, and you have a newfound sense of urgency to get something done and perhaps are much less choosy than before.

Plus there is just the learning process. You haven't seen many deals to really recognize a "good" one vs a "bad" one. So there is also some prudence in searching for a bit before committing. This is where an advisor or coach could help. Use their experience to guide you, not yours.

And maybe what I can read into what you're saying is even if you find the perfect deal as the first one you look at. You still may not buy because you're scared and may not know the difference anyways!
