If you don't understand where you're coming from, with a clear objective and clear direction, how on earth do you expect your peers to understand?
Make sure you know yourself at work; your strengths, your weaknesses, your professional narrative (where did you start, where are you now, where are you going and how?). Also, make a conscious effort to keep your conversations and requests brief, concise and clear.
Everyone at work knows time is precious, and as long as you appreciate that (i.e. avoid being as clear as mud and taking too much of their time, only to confuse them further), you shouldn't have any issues communicating and collaborating with your team.
Bonus: you won't get yourself all muddled up either!
