Unfortunately not everyone has the privilege to not work and focus on themselves that’s why they never improve in terms of the job they land on. Since they don’t have the time to focus on themselves and their skills, they remain only on a specific level and their wages are also the same.

Most people simply don't have enough time for everything. You have to use your time wisely and to be very good at something to be successful. Unfortunately, most people have neither enough time nor enough talent. If you have both, you have an opportunity that most people on this planet never had and would never have - use it!
