"Planning is all that is needed in every step of life. If you plan well in advance nothing can beat you."
Thus, if you will plan and make a schedule how you want to allocate the time, everything will go smooth.
For example, once you are free from your work, plan to devote one hour each in the activities you love to do. Schedule them. Time allocation is very necessary to be happy and successful.
Important thing to remember is: Stay stick to your schedule.
By the end of the day, you will have satisfaction on your face.
That's a great question. I am someone that is very socially active in things that are important to me. Some of them are work related. But you can find a balance, it just depends on what your work schedule is going to be. If that happens then try to move your activities around so that it does not impact your job. If you can't then try to get a new work schedule. In either event, there may be the opportunity to demonstrate some flexibility with your activities and your work schedule.
Work-Life Balance is extremely important to mental freshness.
Good luck and hope this helps.
