Make yourself valuable where something genuinely needs improving.

Value is relational. It depends not just on what you can do but on whether there is a genuine gap where you are doing it. Considerable ability applied where nothing was needed produces very little, while modest ability applied at a real point of need produces a great deal.

Look for the place where something is visibly not working and you have some relevant capacity. That intersection is where your effort will do the most, and it is usually less crowded than the obvious opportunities.
