hi,

if you believe you can't master any techology if you choose then dont choose it, because what you think is what you get, if you think you cant do it you can never do it, but if you think , i got a chance to get knowledge on different technologies, but i will definately master one of them then go for it. Decision is in your hands. Its easy to advice, but its you who have to take the decision. so, believe in yourself.

Thanks
Sushma
