Just as you apply your entire energy and mind to building up a bank balance, if you apply it to finding Liberation, you will find it. Believe me, you can lead a normal life while working, when you have found it. However, If you want to fully dedicate your life to understanding the Truth, it might be necessary to give up things and lead a life of solitude. But once it is found, you still can live in this world and work. The work will be there but it won't be self-centered. It will be for others.
