Rasul Allah (sal Allahu alaihi wa sallam) said: “It is the excellence of a man’s faith that he gives up meaningless work.” [Tirmidhi, Ahmad]
We need to check all our activities and label them to see which belong to the category of meaningless. If the activity is not taking us towards a meaningful goal for any of the roles that arise from our ideology (e.g. Muslim, parent, son/daughter, self, breadwinner,da'ee, etc), then it would be to our advantage to replace it with more meaningful activity.
Anything that does not bring us closer to Jannah and distance us from the Fire is meaningless in the long run, and will cause us to regret when it will be too late to realize why did we bother to waste your time with it.
Life is too precious to be wasted for worthless or meaningless matters. The best use of life is to spend it for something that outlasts life -- i.e. akhira. Life is like a cash register, in that every thought, every deed -- like every sale is registered and recorded.
Life is not lost by dying; rather life is lost minute by minute, day by day, in all the thousand small uncaring ways.
We are here to add what we can to life, not to get what we can from it.
