There was a boy from a middle-class family. one  day he decided to clear UPSC exam and wanted to become IAS officer. That boy bought many books related to UPSC exam and subscribed many studies channels on youtube and parallely took online classes subscription and also settled in a big city. He informed all his parents and family members that he is now pursuing UPSC exam and also told them not to disturb him because he is not going to become an IAS officer so he started his studying because only 10 months left for his final exam. so he worked very hard and used to sleep only for four hours a day but the problem was he could not sustain and he studied for only one month this way and soon his motivation expired and he was now fedup with all his studies. He started irritated by his studies and soon returned back to his boring schedule and he couldn't clear the exam. This happens with every 6 boys out of 10 in our nation. look if you want to become successful then motivation play role for only 1 percent and 99% is nothing but self descipline. From day 1 to day 1000 to day 2000 you have to follow the schedule. When a boxer score a gold medal in Olympics then self discipline is the the only tool behind his achievement but people only know his name that xyz person has won the gold medal but no body knows how much he has sacrificed for 5 gm of gold medal. He sacrificed all his pleasures and  comforts,that boxer has followed the same schedule from year 1 to year 10 but many of us say boring to that schedule he left the junk food for almost 10 years and focused on carb and protein he has worked every month and year and practiced every seconds then he has reached where he is now and he worked day night toiled himself under scorching heat of sun and accepted pain for  himself but many people think he has done for a gold medal no my dear no he has done that to prove in front of everyone that he dont want to be a part of crowd or lead a normal life that he deserves something better and the key to reach your goals is self discipline. Best of luck 👍
