No one can and no one will ever know you like you do...you're acquainted with every single trait and facet of your personality...you know you're vulnerabilities and strengths..you know what works for you and what doesn't...so trust your instincts, work accordingly  and believe in yourself...sure listen to what meaningful people around you have to say...take the helpful and positive aspects from there and apply it to your own strategy and method of proceeding...this might not always give you immediate success but at least it will create a roadmap for it.
