Most people don't believe they hold a scarcity mindset, but a scarcity mindset doesn't have to apply to all areas of life. It can apply to just one.
In our society more is considered better. This puts all of us at risk for feeling as though we don't have enough. Consumerism, which drives the global economy, requires growth, and the demand for more stuff. This has resulted in all levels of society cultivating a scarcity mindset. It just looks different at each level.
Here are a few examples:
There aren't opportunities for someone like me
Not enough money for my desired lifestyle
"Keeping up with the Joneses"
Each situation is different, and to compare equally discounts the unique situation of the individual.
On average, if someone is starting life with loving parents and adequate income they will be more developed earlier than someone who starts with distant parents and lower income. The challenges of each of these people to achieve the same things is not 1:1. By realizing this difference you can set accurate and achievable goals, which lead to positive results and more growth.
Here's how:
Write out your achievements in bullet points and note how long they took to achieve.
Now, determine what next step would be achievable on your path to your desired destination. This decreases the risk of failure by making incremental improvements. Trying to achieve too much to fast is a recipe for burnout - instead focus on 1% a day starting from the here and now.
Comparing yourself to someone on a different path creates reasons why you can't more often than why you can.
This is also a poor foundation for making worthwhile advancements in life - when your actions come from intrinsic motivation you are more likely to be resilient in your pursuit. This new way of objective thinking creates opportunities where there were gatekeepers. And without self imposed constraints more people than ever can rise to to their potential - whatever they decide it is - by working at their pace, steadily and without excuses.
