Realize that a perfect solution is not feasible (it does not exist). Not even an optimal solution for your particular problem is feasible (too many unknowns about both the problem and potential solutions, impossible to uncover and analyze them before hand).
Realize that if you had chosen another solution, you would have other issues. Not "no issues". Probably not even "fewer issues" or "less severe" issues - just as high a chance
Realize that most technology choices actually have very little impact on the business. If one uses A or B, it does not matter much to do whatever it is your company does. Very few tech choices have the potential to kill the company/unit/product.
Realize that once a choice has been made, worrying about it does not help anyone.
So the goals are not perfection. Not anywhere close. Just something that:
1) lets us move forward now (avoid decision paralysis)
2) not worse than before (if so, just stick with what you got)
3) good _enough_ to deliver the needed business value
4) does not paint ourselves into a corner. Then we can always fix and improve things later
