There is an old saying, “karat-karat abhyas ke jarmati hot sujan” that is, if you work hard, you will surely succeed. It is also said that if the mind wins, the world wins.
Although we all work with our hands, feet, ears, mouth, etc., we do it with the senses, but it can be done only when our mind wants to do that work.
According to Shrimad Bhagavad Gita, by practice and detachment, the mind comes under control. In order to achieve your goal, if you have disinterest in worldly things and attachment to the goal, then success will surely come.
Generally, if a person wants to penetrate the target, then he needs two things, hard work and luck. Hard work is done by its own effort in which the soul, intellect, mind and body etc. and luck is the grace of God. Having both, no goal of the world is impossible.
To sum up, keep doing virtuous deeds in life, so that God gives good results of your virtues and do not keep any shortfall in our efforts, hard work or rather in dedication, then success will be in our grasp.
