TS, once you pick up, it's almost more or less confirmed that it's a point of no return....and it's not cheap to buy "medicines" for the contagious BBB virus. Like Tucksoon mentioned, there is NO cure for this virus...
OTOH, if you are doubting if you should, then you shouldn't. Think carefully...
Step 1: Work out a budget.
Step 2: Head down to shops and try out the cameras.
Step 3: Rent camera and lens to try.
Step 4: Reading up photography books/websites and watching YouTube video helps.
Step 5: Buying used DSLR/lens might be a good option too
bro, can try to also read this thread also if you are still deciding...All about compacts..Don't be too intimidated by the word "compacts". Photography is not all about DSLRs/SLT/Mirrorless/Flim cameras (or whatever they call it)
If you really are not sure, start off with just a P&S, a simple digital compact camera first. Then if you think think you like to expand your photographic horizon, by all means.
The above replies telling you to not start, maybe a bit over the top. They assume you want to start with a dSLR. Remember, some professional photographers can take wonderful shots with a $300+ camera! So just go ahead and start shooting, but brush up on the theoretical side, else the pictures you take can result in disappointment.
