Make a pros and cons lift of each option
The one that comes out the best is the one you pick. make a pro +1 and a con -1, this way you can tally up the scores and pick which option comes out on top.
Ask others for their opinion
Try to ask people who are unbiased and who won't be impacted by your decision but still care about the choice you make. If you ask someone who is biased, they will pick the choice that will benefit them.
Set aside some time
Don't just leave it until you have to make the decision on impulse, as you may make a choice you didn't mean to make. If you have an advance to make the decision, try to do so.
Sleep on it
A good night sleep can clear your head and so when you wake up, your judgement isn't clouded.
Hope these help
