I feel you, there's a certain feeling of ephemeralness if you step back and think about it that way. Put another way, "The days of our years are threescore years and ten; and if by reason of strength they be fourscore years, yet is their strength labour and sorrow; for it is soon cut off, and we fly away".

The thing that changed this for me is, no joke, having kids. This brought me away from the feeling that life is fleeting with little point to the minuscule things I may accomplish and showed me a grander scale. As an engineer, I'll never be a Maxwell, Shannon, etc., but I can raise the generation to come in a way that - though I may never know it - could have an incredible influence on the world.
