Do not give up on any idea, as insignificant as it may seem. Give them a chance to see it in action. At least talk about it with someone. That’s a good pre-put into action strategy—to warm up, let’s say! 
You should not allow doubt about your self-trust to grow in your mind. If a thought comes, it is an expression of yourself and what you are doing every day. It should be respected for what it is, not segregated somewhere in oblivion and forgotten about. We can divide actions into three steps:
1) wish to grow;
2) relative thoughts or ideas;
3) actions to fulfil 1) and 2).

Usually, step 1 requires inspiration or a reference person, which allows us to stay motivated. It should not be strictly a relative. Once you decide which field to become passionate about, just work hard and chase your goal! It is very simple. 
If you are willing to grow a business or develop skills that open new doors, you should pursue them without ever giving up. It is also important to raise awareness about how to concretize those ideas and dreams. 
Sometimes our mindset is stuck in the same binary. To open up new ways, it is important to experiment and try to be open-minded. What you have to do is change your strategy about how to perform a certain action. If the job you are doing suits you and brings you satisfaction, it is important to adjust point 3) accordingly to the environment in which you are living and your present knowledge of the business.
It is important as well not to be scared to make mistakes; otherwise, there will be a constant break preventing us from going forward.

Check the following types of actions for better performance on the second and third points listed above:
– open a business account on facebook to advertise your business;
– write a blog to keep the mind fresh, ready and eager to find new strategies;
– call people that may be interested in collaborating with you;
– create polls and surveys to keep you updated on client needs;
– expose yourself to the environment you like to work in, maybe asking for information;
– volunteering can be a good option when starting up, helping out and learning new things;
– create a newsletter, a vlog, or be consistent on a social media platform you like to advertise your business with or simply express yourself;
– maintain a website to connect and stay focused on your goals;

About this last point, WordPress actually offers a completely free blog website. So it would be a great idea for those who are not willing to invest in money, but want to give it a try and experiment.
