Change is the inevitable part of life. No matter what you do, situations around you are destined to change.

Environment eats your plans for breakfast.

Change is neutral — no hard feelings

Attaching sentiment to a change will take away the evaluation part. Categorizing change is okay, but letting it affect your behavior is bad.

Change is inevitable — plan for it

Plans always come down to two alternatives: desirable and not desirable. Change might impose a switch of tracks. Be prepared.

Focus on the next thing

What had to happen, has happened. Dwelling too much on the past distorts the ability to think straight. Life is only going to go forward, so better focus on it.
