We sometimes minimalize our need for “me” time by thinking about how we’re denying attention to other things that are important to us, such as our family, our friends, our gym time, our book club, the lawn, or whatever else. We feel selfish taking the needed time out when there’s so much left to do. However, if you run ourselves into the ground we’re not going to be much help to anyone, and you won’t be able to be fully engaged in your activities anyway. Our health is vital, and if you think these obligations can’t succeed without you, think of what might happen if you become sick and have to set them aside for a longer amount of time. We need a little time to recharge our batteries.
Shi we all have the same 24-hours in a work-day, nobody has more. Assuming we spend 8-hours a day at work and get 8-hours of sleep, that would leave us 8-hours of free time. Be careful that you use your “me” time for leisurely activities and don’t push yourself to complete anything. Simply enjoy the time out. Indirectly, taking time for yourself may also improve your interpersonal and business relationships, making you a better partner, parent, or employee.
There are lots of variables here. This includes commuting time, if your job expects you to respond to texts and emails while "off-duty," family responsibilities (soccer dad?, band recitals, etc) hobbies you are committed to (gym membership?), how much sleep you need, social life, etc.
Let's say you work 8-5, with a short, half-hour commute. If you can jump out of bed, jump in the shower right away, grab breakfast before you leave. . . .maybe get up at 6-630. If you plan on hitting the gym before work, probably make that about 430-5am. Or, you can hit the gym after work.
Now, you get home. Do you really want to go DO something, or do you want to just unwind for a while first? What are your meal plans? It takes time to cook and eat. Do you need to walk the dog?
Add to all this, when do you plan on doing chores? Laundry, house cleaning, grocery shopping. If you save them for the weekend, it REALLY cuts into your weekend! It's nice for those days to be totally free.
So, with all that in mind, let's say you are single, no dog, go to the gym before work, not in school, and go to bed at 11 pm. That gives you five hours each evening, "free", plus your weekends. But, as you can see, taking on a job that expects you to be available after hours, getting a family, or going to school will start to whittle away at that. Hope this has helped!
If you are an entrepreneur, for example, you are happy to dedicate some extra hours to your work. if you are working on an exciting project which is giving you a lot of new skill sets or a career progression opportunity, yo wont mind adding some extra hours to your work life.
Also consider doing things in smart way rather than hard way (for this you may need to learn some tools and techniques (you can do so online).
On the other hand try to keep little balance between personal and professional life as your well being contributes a lot in how you deliver in your professional life.
As a minimum, I believe you can aim around 10-12 hrs for your personal life.
