How to avoid loneliness when you don't have friends
Join a gym or community fitness center.
Use your body's need for physical activity to interact with others. Sign up at your local gym for a challenging group class.

At first, you will feel unnerved by participating in a class full of strangers (and potentially making a fool of yourself). Persist and you will find that group exercise can provide motivation, accountability, and camaraderie.

How to shake off a bad mood
Exercise.
Bad moods can lead to lowered energy. However, exercise cannot only help you feel more energetic, but it can help turn your bad mood around.

Try traditional types of exercise such as playing sports, running, walking, lifting weights, and doing sit-ups. Or, if you are feeling adventurous, try fun physical activities such as: doing yoga, dancing, hiking, rollerblading or skating, skateboarding, paddle-boarding, bowling, and kayaking.

How to small talk for successful business networking
Introduce and initiate.
Go ahead and initiate with a hello! Even if you recognize, or slightly know someone, re-introduce yourself. Be aware of how he introduces himself (you may know him as charles, but maybe he goes by chuck) and use his name throughout your interaction.
This will help you remember it in the long run and also establish a personal connection. By taking ownership and initiating a conversation, you will feel more in control to drive the direction of the exchange.
