$1.50 a day can be very do-able. Important thing is to set goals that push your limits, but that are still reasonable. Then work your mindset around that gathering everything you need to work towards that. My very first time doing affiliate marketing I made a net profit of about $150 for the first month. Not too shabby, but I had invested a lot of time and money in learning direct marketing strategies before ever doing any affiliate programs.
The next month I only made about $40 net profit. There are waves and ups and downs when you start off in anything so don't think that whatever you've done is any indicator of where you are going. It's a matter of practice and planting seeds and growing them
Get your hands on everything having to do with marketing, NLP, sales and self improvement you can. It will pay off big.
All the best
