Answer:
Yes and no, in my opinion, it all depends on what the encounter was or the choice you made that would change your future.
Step-by-step explanation:
If it was a positive encounter or a good choice then definitely but if it was a negative encounter or a bad choice then no. If you were trying to start a business and someone told you that you would fail and your business would never succeed that doesnt mean you should give up all because of that. But if someone were there helping and supporting you along the way then yes let that encourage you, its all about how you look at the situation.
