When you look at Facebook and Twitter, people do not seem to care that much about their profile pictures... but when you get to LinkedIn, that profile picture matters A LOT!
Matter of fact, if people have a profile picture of them smiling, they come off as more reliable. How do you make sure to have a great profile picture?
1.What's behind you? No clutter, make it simple and clear
2. Lighting is super important
3. Try not to take a selfie, try to use a tripod
4. SMILE - not laughing, smiling makes your more approachable
