You cannot modify, alter or control time; it is our master. What you can modify, alter and control, however, is your effort.
Naturally, time cannot be ignored; it is a very relevant factor. But without consistent directed effort, you will achieve nothing, effectively rendering meaningless whatever time you’ve spent.
So when you are working towards achieving anything in life, you are best served by focusing your energies & attention on the quality & magnitude of the effort you are directing to the task at hand, rather than paying a great deal of attention to the time it may take.
