Is it too much ask?

While warming my tea and sipping it todat morning, it finally struck me.
Why nothing ever makes me completely happy and satisfied. Now I know -It is just me. I am on maternity leave and I still have 4 weeks left. I plan to join back for atleast 3 months and then I plan to quit and stay home.
So far it is fine, but the problem begins when the guilt of leaving my kids for 12 hrs a day starts hurting me and at the same time I also regret missing the business training I midded while I was on leave. That could have helped me going to next level...not that I do not enjoy taking my 5 year old for soccer classes, my heart swell with pride as he reads the book in library sitting with me. My 2 month old steals my heart away with every smile and so many times I felt moisture in my eyes.
But then again....
It is wrong if I want this and that as well. If my heart can not be content with one thing. I want to find out my worth in the world while I also want to attend every easter/christmas or valentine party with my boys.
I want more than 100% from my life and it can only give as much it can.
Thank go that it was my family who decided who should I marry or else I would have spend years looking for just the right one, no wonder I resisted as much as I could. Not that I am perfect or I seek perfection, It is just that I want a little more. May be 24hrs day is good enough for the rest of world, there must be few more out there who could use a few extra hours. Afterall there is so much too be done and there is never enough.
Is there something wrong of somebody like me is out there seeking more from life and never giving up to become content with whatver has been served?
