It has always been assumed that being successful means learning from those who have already achieved their goals.
It's true that having a guide or mentor like The DIY Entrepreneurs is an advantage to an Entrepreneur, but this is also the fact that everyone can't find a mentor who is there to help and support in any situation.
The biggest motivation for any individual is to challenge himself as it not only encourages you to give your best but also allows you to know your strengths and weaknesses which will be quite helpful in coming up and performing better.
For any new entrepreneur the initial phase of the business is quite tough as it takes time, money, patience, etc but if you love your work and care about your interest in work then just go ahead, you will achieve your goal with strong determination and dedication.
As you are new to the business world, although you have an idea which you get through the experience of known people when you are entering in the business world where you have to compete with big giants then you have no idea what can happen in the next moment so just ready for such situation and always be prepared for risks.
