I don't think that your past should be affected by your future. This is because your past start by pointing out that your ability to envision the future is influenced by your memory from the past. This is because, you tend to use memories of past experiences to predict what your life will be like in the future. It is easier to use your memories when the future you are predicting is very close in time.
Yes and no, in my opinion, it all depends on what the encounter was or the choice you made that would change your future.
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.
