Don’t just do something because it’s a trendy idea… – Jerry Greenfield.

..and will make you a lot of money,

What’s the reason?

After all business is all about having an idea
about what people want and giving them at a profit;

Yes, it’s true but every product has a life cycle,

some factors are fixed while some are variables;

and not all business ideas succeed,

the few that succeed will at some point, run into difficult times;
when trendy becomes obsolete and to survive,
an entrepreneur must sacrifice personal comfort
to make things work.

But if the business is not your passion,
it would be near impossible to make the required personal sacrifice
and get through tough times,

Don’t just do something because it’s a trendy idea and will make you a lot of money. The reason I say that is because any kind of venture involves going through difficult times. If you’re doing something you are passionate about and really believe in, then that will carry you through. – Jerry Greenfield.
