"Theory is impractical and thus no good" vs "Good theory is the most practical approach to problems"

When reading this two different statements,  I agree more with "Good theory is the most practical approach to problems". The reason I take this position is because we need theory to resolve many problems in life. Theory makes everything more easy to understand and it helps predict what the outcome of any situation can possibly be. 

Theory helps to answer the "why" in many situations. Theory  evaluates the problem in different stages and find different solutions to give you more options to approach the problem.  Without theories so many businesses and big companies will not be successful today. 

Good theories makes us analyze the situation and make rational decisions. It helps us kind of predict what could happen and when. Not all theories are good but even the bad theories can point you to a better direction to approach the problem.

In conclusion "Theory" is the most practical approach to our every day dilemmas and help us find a better  solution to any problem in  life, jobs, family issues, and personal decisions.
