Satisfaction does not lie in material achievements or professional success alone. By making small and simple changes to your inner attitude, you can significantly increase your life satisfaction and become a happier person.

Be nice to others. As trite as it may sound, spontaneous kindness and a nice smile for those around you can immediately improve your own mood and benefit from long-term positive effects.

Meditation has been proven to reduce stress, nervousness and depression, factors that greatly reduce your life satisfaction. You don't necessarily have to become a full optimist, because people who see a glass half full as half empty can be just as satisfied with their lives. The more you realistically accept the uncertainty of the future and the possibility of failure, the more at peace you are with your circumstances.

Having clear goals triggers positive feelings and suppresses negative ones. As the saying goes: the journey is the destination. It is not about achieving a goal, but about working towards a desired goal.

The ability to be happy is only half genetically predisposed. The other half can be learnt, which means that anyone can become happy, even later in life.

You should treat people who are important to you in life well and nurture your relationship with them. Friends help you to be strong in difficult times. Conversely, you experience satisfaction when you help and support your friends in a difficult situation.

Stay true to your own self. You can enjoy personal successes better if they actually come from within you. If you delude yourself, there is no fulfilment.

Smile and laugh, even if you don't feel like it. Smiling, even if it's not entirely genuine at first, promotes positive feelings in the brain. The more you fake your smile, the more genuine it will become over time.
