Lifehack.org is a self-help website that offers classes, articles, and other resources to help you improve various aspects of your life (such as overcoming procrastination, dealing with relationship issues, and eating healthy). While many of the writers on lifehack are professionals in a variety of fields, it’s still a good idea to read the information critically and look at other sources—for example, talk to your doctor or use a website like Pubmed to research any claims about health and medicine.
