How can we make our life meaningful?

hey friend I think everbody think once in the life and he always tried for that but at last finally the get that this life has also wasted as others. so since you have reach that point then I would like you to suggest and after using this you can able to make life meaningfull your self ,since what others experience can not be your experience so make your own experience for making your life usefull for that you have to do nothing just use your half an hour of the day for sit , without doing nothing, you got my point , what ever you are doing you do as usual but just give only half an hour for what I am saying and at least six month you will have to do that and after 6 month you can take your own decision for make you life meaninig full , in this half an hour you will have to do nothing just sit in a peace full place (morning would be good, if not possible then before going to sleep you can do this on you bed , but without disturbing to others and if possible without telling to others )and watch what thoughts are running your mind and don't apply you thoughts just watch what though is running your mind , means you have to do 'thought less watching ' and if you do that one month you can feel the change your own , what you have to do after that just wait for that .....

There are many things that make my life meaningful but the foremost of these is work. I would be lost without work. I like to think that I am doing something to make this a better world. Cheers!!
