First, tough love instills independence. If you want something, it is up to you to work for it. Others may help you, but no one is obligated to lend you aid. You are responsible for yourself and your actions. You are also responsible for any consequences that may come as a result of your actions.
Second, tough love teaches you to take criticism. Criticism is not the end of the world. The only way to get better at anything is to have specific things to improve upon. Oftentimes, people's criticism highlights weaknesses that can be turned into strengths with hard work and dedication.
Third, tough love teaches you how to be okay with being told "no. When one door closes, another door often opens. Being refused help or an opportunity or anything else does not mean your journey is over; it means that it will turn in a new direction.
Fourth, tough love teaches you how to work hard. You can't expect to just get by on handouts and participation trophies in life. By not getting what you want all of the time, you develop a strong work ethic that can be applied to many situations in order to achieve your desired goal.
Finally, well-earned praise feels so good in a tough-love environment. There is nothing better than working so hard at something you want to badly, and finally getting approval, credit, recognition, etc. for what you have done because you know you really deserve it.
