“Many of life’s failures are people who did not realize how close they were to success when they gave up.” – Thomas Edison
Don’t give up. You may need to redirect your focus or take another approach to solving the same issue, but don’t quit. Quitting when things get tough teaches you to take the easy way out. But it is only easy at that time. Every time you quit, you are hurting yourself. You’re hurting your self-esteem, your reputation (among others), and your aspirations for a better future.
