My answer: Gardening.
I used to like swimming, reading, shopping, listening to music and collecting phone cards.... I still love them. But my main focus has been shifted to gardening lately.
Reason? The plants kept me alive.
Whenever I tell someone that I love gardening and that I have 18 pots of plants in my balcony, you should look at their expression! It's like as if gardening is the weirdest thing to do on earth. But true, it is rare for youngsters nowadays to like gardening as compared to clubbing, chilling, water sports, etc. With all the excitement out there, gardening seems a tad boring.
Granny loved gardening and she had "green fingers". Needless to explain further, gardening serves a remembrance of her and thus kept me alive. They are the only so-called living things apart from my family members who are seldom home.
I will devote at least 15-30mins of my time daily on watering, fertilising, re-potting or propagating the plants... sometimes chatting and feeling them... somehow I just felt that my presence and appreciation of them wld enhance their growth.. to me.. they're my frens.. I listen to them as well as to talk to them. That's me... you may think that it's weird.. har?
This is how much I commit to a hobby. And it has become somewhat my responsibility...
