Sometimes you may be engaging in an activity putting all your energy, resources and giving it your best, but you may not be making any progress, how about you take a break( this doesn't imply that you are a loser), it's just an avenue to see why things are not working. The fact that some persons are thriving well at somethings doesn't mean its the best for you. Sometimes, all you need is to discover what is best for you and what you can do very well happily.

Quitting a job or business is not bad if its for a good course, but quitting the zeal to improve and press forward is not a good decision. That thing you are doing will definitely work out if you do not give up. No matter how rough the road may be, be determined to walk on it and you'll be successful.
