I wish, I wish, I wish. If only, If only, If only. The common phrases we often say and often hear. Then when we see our friends or relatives on their death beds, we tell ourselves that we should live our dreams and plans as we do not wish to have regrets just like they did. A week, a month and perhaps a year go by and then we slip back to our comfort zones.
Let alone at one's last breath. Many people have plans to, for example, renounce secular life only when their children have married, or do charity work only after their house mortgage has been paid off, or procrastinating on something and when they are ready to do it, they are already too old and physically too old by then. And regret sets in.
For someone who has no dharma, you can understand why. But HHDL said that the main purpose in life is to be of benefit to others, not oneself. So stop procrastinating, stop justifying and just go out there and do it! As for me, i do not want to be at my death bed wishing and regreting. To put it on a lighter note, it is just too many things i need to focus on at my dying moments; the visualizations and all. I do not think I cant handle all that coupled with regretful thoughts of what I should have done and didnt do.
