There is a famous warning against “He who hesitates.”
To update and make this old saw more p.c., I will say “S/he who hesitates is lost.”
Proverbs about vacilating and disaster can be countered with one about “looking before leaping,” aka considering the consequences before an action.
Be decisive, but be sure to make the correct turn in the road. There’s an app for that, of course, and you likely are a consumer of that product, the GPS.
