Death is the ultimate reality and we can't take our eyes off from it. Life needs a constant improvement because to grow is to live. We articulate our thoughts and make many to-do-lists or take oaths that this we do and this we don't, but from my perspective what I have seen that there are some people who give up before accomplishing their desirable result.
We don't look up for solutions and by and large we don't delve rather we take shortcuts and if a pause occurs we stop pushing ourselves, we learn the whole dictionary , terms and we learn the ups and downs and ohhs and ahhs but we don't apply them in our life affairs or when life puts us down.For e.g. In the above paragraph I write constant improvement this is a term to learn but to implement as well.
Whatever your passion , whatever your goals are , whatever the kind of work you plans are just do stick to that and don't look back.
It's better to do what you want to before the energy falls or your will started to weaken up. In a nutshell do it before you die.
