I am an entrepreneur who does not like to be in the limelight. Am not a big tweeter or public figure. How can I still build my cred?
Before building your credibility, make sure you accomplish some goals so that you gain experience from them. Failures are great since they teach you a lot.
From there, build your online personal presence so that if anyone searches you on Linkedin or Google, they can find some information about you.
Then, join many groups online either on Linkedin, Facebook or other websites. From there, try helping people within the community that could benefit from your expertise.
This is how I did it myself and it works great. Baby steps do help!
Hope this helps.
