Step 1: Start with simple circuits. And implement them on bread boards. Don't go for the printed circuit boards yet. There are many circuits out there for beginners. Choose one and implement it. Vary the elements in the circuit. For example if the circuit asks you to use 10k ohm resister use a 100 ohm resister and see what happens. In this case there might be drop in voltage(I believe, my memory is quite vague). To measure this you use multimeter. Learn how to do that. It is fundamental for any one wanting to play with electronics stuff. (P.S: If you are from India there is a magazine named "Electronics for you". If you have the money buy it. It is quite amazing. I haven't read it 6 years though so I don't know if the quality is still good)

Step 2: Start reading the datasheets of different Integrated Circuits that you might use in your circuit. Its not that hard. Once you understand what Vcc, ground etc., are it becomes really easy.

Step 3: Try and solder the the elements that you used on a board. Soldering is a basic skill that many engineers I know lack. It is good to know it. I have fixed many broken radios and other electronic items using this skill.

Step 4: Start designing printed circuit boards on a software and send it to a company and print it(there are other means to do this too).

Once you cover this, you can do a lot of really cool stuff with electronics. I hope this helps.

Note: This makes you an amateur. Now if you want to learn about FPGAs and other stuff, then its gets a little tricky. You might need a book for that.
