Lack of fulfilment?

I don't know why I feel like ending my blog lately. Many thoughts come to mind, but I suddenly feel that they are too personal to share with everyone. This adds to my frustration. Although it's unhealthy to start feeling that there are secrets to hide, there comes the recent realisation that I do not want to be read as easily as a book. Maybe this is insecurity at play, I don't know.

I met up with 2 JC good friends tonight. One I haven't really talked to for 2 years, and the other we have been keeping in touch occassionally. They have just started working life for the past half year. We started talking about how one's energy depletes with age, and how one has to put in some real effort to participate actively outside working hours in order to continue living a fulfilling life, unlike while in university. Sometimes, when I see certain friends becoming stressed by work, I feel disturbed and start wishing that I could do something to help. But how much can I do when I lack even the energy to add more fulfilment into my own life?
