You are in a period of Shani Mahadasha dasha and Shani antardasha. As your Rashi is Gemini, you are also in the period of Shani Sade satti, which is the reason for your obstacles, failures and limitations that you face in your life. The period for income is there, but it will not give you the desired results. Do shani puja and you will get good results. Also read Hanuman chalisa daily.
