Learning acceptance is the same as avoiding your, to this point, natural response :)
Some spiritual texts (stoic philosophy) place an emphasis on guarding your impressions to external events (e.g., deciding I have a flat tire, this is bad, my day is ruined) because if you solely restrict your judgement of good/bad to things in your control then you'll never fail to avoid what you want to avoid.
Personally, I think the answer lies somewhere in the middle: in general you should seek to embody Marcus Aurelius' "This doesn't _have_ to affect you" quote but there are also times where being affected by things is a natural and healthy human emotion and at those times you should not avoid feeling them and instead practice sitting with them, understanding them, and learning from them.
