nobody wants to put you off at all
do it
go for it
but the main thing as always is money.
if you have enough money nothing else matters but the problem is people think its cheap to live in spain.
sure it can be cheap if you eat bread and water and live in a shack.
but just make sure you have a lot of savings to last you twice as long as you think you will need.
if you think you can live for 800 a month double or treble it.
if you think you will get a job in 6 months double it or treble it.
be prepared and have lots and lots of money saved up to make it all easier.
sure you will struggle with some things and it will make it more fun overcoming challenges but people turn up with no job and not a lot of money and wonder why life is so hard.
prepare for everything and then prepare even more.
if you can get a job before you come here do.
if you think it will be easier to get a job when you are here thats not quite right because you are pouring 1000+ euros a month of your savings into rent and living so it can get desperate.
