Frequently, when you spend a lot of time, money, and energy on a worthwhile project, some people will oppose your plans. It is easy to feel discouraged in such situations.
Rabbi Yechezkail Levenstein wrote to someone facing such a challenge, "Don't pay any attention to those opposing your work. Every worthwhile project will face some obstacles and opposition." When you realize that it is normal for people to oppose you when you try to accomplish, you will find it much easier to tolerate and overcome the difficulties of that opposition.
